AN ANALYSIS OF THE DAILY RADIAL ACTIVITY OF 7 BOREAL TREE SPECIES, NORTHWESTERN QUEBEC

摘要

In the 'Des Vieux Arbres' ecological reserve situated within northwestern Quebec, 40 band dendrometers were installed on 7 of the major boreal tree species. This late Spring-early Summer daily radial registered in 1997 was related to daily weather variables. For each Tree species, the daily mean I)cumulative radial increment and ii)radial activity indexed series ob- Tained by first-difference standardization were analyzed. The results indicate the existence of strong Similarities among the 7 species.
